DELIVERY APPARATUS FOR FEEDING MECANISM.

Application filed March 1, 1928'. Serial No. 258,213.

A delivery of material, for example, heavy sheet materialtoasupport onwhich the material accumulates. One of the objects is to provide anapparatus of this-kind with an auxiliary support movable into and out ofthe path of thelmaterial passing to the first mentioned support,- so asto permit Vcontinued operation of the feeding mechanism while theaccuinulatedfmaterial is be- .ing removed. y v

Y Inone form of the invention, the mechanism may be 'used to feed large,heavy sheets from a printing pressito a delivery table, or platform, onlwhich the sheets accumulate/in a ile. f

ISuch presses frequentlyare provided with suitable lmeans for to adelivery table, the delivery table being lowered relative to thedischarge end ofthe delivery carrieras the'pile of sheets o n the tableincreases.

f However, theusual delivery tableiand the means at present employed forlowering the same, are not entirely satisfactory in handlinglvery heavystock, such as large card-v' board sheets. A pile of such sheets on thedelivery table is of greater weight than can conveniently be handled byhand, so it is necessary to handle the same by means of cranes ortrucks'or the like, which, of course, takes time and, heretofore, it hasbeen necessary to suspend the operations of the press.

.pending the removal of the pile of printed`r sheets. `It is, therefore,one ofthe objects of my invention to provide an auxiliary supportmovable into. and out of 'the path of the sheets discharged from thedelivery carrier, so as to support said sheetswhile the loaded table isbeing removed and replaced by.

. tii-iuous operation `of thexpress.

f Such ana'uxili'a'ry support, however, must support a pile of the heavysheets and eventually dro'p them onto the table withoutcausing a verysubstantial horizontal displacement of the sheets,

transferring the sheets" 4and modifications which come -along the Fig. 5isa front-view ofthe device, with.

an empty table, thus permitting'the cony even though anapproximately,horizontal movement is, im-

parted to the auxiliary support. I have therefore devised an auxiliarysupport movable from beneath the superimposed sheets Without frictionalor sliding contact therewith, and this constitutes another object of myinvention.

Furthermore, a self lowering table for use with heavy stock must beositively lowered step by step, or in sync ronism with the -delivery ofthe stock thereto, in order to have a minimum drop of the sheets fromthe discharge end of the delivery carrier to the top of the pile on thetable, and it is a further object of my invention to accomplish theaforesaid purpose and valso to provide an associated means for quicklyelevating the table to said minimum distance from the discharge end ofthe delivery carrier.

VVit-h the foregoing ,and other objects in View, the invention comprisesthe novel method, construction, combination and arrangement of partshereinafter more specifically described 'and illustrated in theaccompanying drawings, wherein is shown the preferred 'embodiment of theinvention. However, it is to be understood that the inventioncomprehends changes, variations within the scope of the claims hereuntoappended.

' In Fig.I the discharge end of an extension delivery carrier A- of aprinting press (not. shown),

said carrier consisting of an endless belt 10 passing overl a pulley l1..The printed sheetsare deposited upon theupper run of l f c l a c isa-sectional diagrammatic viewv 1 of the drawings I have-shown A /alinedwith the delivery carrier A for the t' reception of printed sheetstherefrom, and,

due to the Weight of the pile of sheets on they loaded table-12, it isexpedient that'fthe Asheets and table be removed together and thenreplaced by an emp-ty table.

The'table, or platform, is removably supported on beams or members 13extending transversely beneath the discharge end of the delivery carrierA a suitable distance forwardly therefrom to permit the sheets to bedeposited by gravity upon the table 12 which rests upon the top of saidbeams. It will be readily seen that any selected size table or platformmay be placed upon the beams, and, as will hereinafter appear, theplatform -may be'readily removed from the beams when loaded.

The beams 13 are secured to the lower ends ofnchains 14, each passedover a sprocket 15 mounted upon its respective one ofthe hoisting shafts16. There are two of the shafts 16, one at each side of the top frame 17of the device. In the embodiment shown,.the shafts 16 are normally urgedto rotate infop-v posite directions, because the loaded run 14B of eachof the chains 14 is on the inside face of one of the sprockets I5, theweight of thesheets and their support placing the said loaded runs 14Bof the chains under tension. `The free ends of the other runs of thechains .terminate in hand holds 14A, for

use, when desired, in elevating the platform,

although I have provided other means for this purpose, as willhereinafter appear.

For lowering or-elevating the delivery platform l12 I provide amechanism embodying means for lowering the platform step by step insynchronism with the delivery of the printed stock thereto, so that thetop of the pile of sheets will always be at a -selected minimum distancebelow the dis charge end of the delivery carrier A'. I also providemeans selectively and se arately operable from the lowering means orelevating the platform so that the top of the same, or

the top of a pile of sheets thereon, may be f positioned at said minimumdistance belowy the discharge 'end of the carrier AL i For l theforegoing purposes I provide wormgea-rs 18, loosely mounted on the for-W-ardends ofthe shafts 16, said gears 18 beingt'in mesh with worms 19`mounted on the respective ends of a shaft 20 extending across andsupported by the forward portion 4) are piv! ,pawl engages a ratchetwheel 22 klixed to one of the shafts 16, each pawl being spring set tooppose the lowering of the platform 12. However, the loosely mountedWorm gears 18 may be rotated to lower the platform or table 12, and inthis event the ratchet wheel 22 will follow theV pawl 12. The worms 19are respectively right and left hand, as shown in Fig. 5, and theytherefore rotate the gears 18 in opposite directions suitable to theproper rotation of the shafts 16 for the purpose of lowering theplatform 12, and inasmuch as the gears are connected together by the`medium. of the shaft 20, the opposite ends of the beams 13 will belowered equal distances so that the platform 12 thereon may bemaintained in the desired horizontal plane. Each end of the shaft 2O isextended beyond its bearing housing has mounted thereon a pinion 25(Fig. 1) operatively engaging a gear 26 journaled on la stud 27 .mountedon the frame 17. A ratchet wheel 28 is fixed to the gear 26, )and a pawlarm 29 is journaled on the stud 27. This pawl arm carries a pawl\30vadapted to operatively engageethe ratchet wheel 28 for movement of thesame in a direction to ,lower the platform as will hereinafter ap- 24and lone endl pear. The pawl arm 29 may be operatively mounted Aon therearward portion of an intermittent movement to the shaft 20v throughthe pawl 3(7), ratchet wheel 28, gear! 26 and pinion 25, and thus to theshaft-S16 as described in a direction proper for low ering the platform.

Inasmuch as the pawl 30 engaging the ratchet wheel 28 imparts a movementto the shaft 20 only in @the direction necessary to lower theplatform',fw\l`1ile each worm 19 and.

worm gear 18 normally lock the adjacent shaft 16 against rotation in onedirection independently of the shaft 20, I have provided the pawls 21and ratchet wheels 22, heretofore described, as ameans for unlocking theshafts 16 for elevating movement only.

To provide for the elevating movement, Athe shafts 16 are 'each extendedforwardly and one of the shafts has mounted thereon a pinidn 34 (Fig.5'), meshing witlra pinion 35,and a sprocket wheel 36 issecured to thepinion 35.` The other shaft 16 has a like sprocket'wheel 37 mountedthereon (Figures 1, 3 and 5), and a sprocket chain 38 is passed l41passed thereoverg whereby the operator may impartan elevating'movemcnttothe shafts v'16, the ratchet wheels 22 (Fig. 4)

turning independently of their respective pawls 2l so as to permit suchmovement. In this connection it is to be understood that the worm gears18are not fixed to the shafts rest upon a truck 42 provided for theready As the depth of the pile of sheets 23 (Fig- 'ures 1 and 2)supported upon the platform 12 increases, and the platform is .loweredcorrespondintgdy,4 it is iinally brought' to transportation of theplatform with its pile of sheets to any suitable destination. ttotarymovement of the shafts 16, lowers the beams 13 from engagement from theplatform 12, and they may then be swung to one side clear of theplatform for the removal of the same.

One of the objects of my invention is to permit the press to continue inoperation While the loaded platform is being removed, and for thispurpose I have provided an. auxiliary support C movable into or out ofthe path of the sheets discharged from .fthe' delivery carrier A, whichauxiliary support is extended into the path of said sheets and over theplatform 12 a sufficient length of time before. the platform restsfupoii the ,truck 42 to insure that the pileof sheets 23 on the platform12 will pass under the frame 17 when being removed, and further Atoprovide a temporary support for Athe sheets 23A that are printed whilethe loaded platform` is being removed. and replaced by an emptyplatform.`

To -illustrate a suitable auxiliary support I have shown a shuttercurtain 44, as diagrammatically illustrated in'k Figures 6 and 7,extending across and below the discharge lend of the carrier A, andhaving one end fixed to a cross member45 mounted in: the rearwardportion of the frame 17, the. other end being fastened to a rotatable,Adrum 46 extending across the frame bclow'the inember 45, and the said:curtain 44 is intermediately supported by and passedover the forwardface of a Jroller 47 journaled in boxes 48 slidably mounted on ways749supported v by opposite sides of the frame 17.

The rollerl 47 is horizontally disposed,v` andthe upper run 44A (Fig.`7) oftheshut-. ter .curtain passed Y from the member 1:45 over thefrontiere of Ythe roller 47,' wh1ch- -ofv lthe pile.

roller-is adapted for movement into or out of the path of the sheets`discharged from the carrier A, thereby extending said upper run ofthecurtain 44 in a shutter-like manner over the platform 12 and into saidpath. The lower run of the curtain extends rearwardly from the roller 47and is wound around the drum 46 a sufficient number of times to providethe requisite length of curtain.

Spaced u wardly in parallel relation from each o the ways 49 isa rack50, supported upon brackets 50A mounted on the frame 17, which rack isco-extensive, with the ways, and operatively enga-ges a pinion- 51 torotate the roller 47. This roller is provided with two pinions 51, oneat each end, and-there are,two of the racks 50. As the roller 47 isextended to form, with the curtain 44, the said Vauxiliary support, a

rotary movement is imparted. to the roller,

and both ends of the roller are positively driven/by the racks andpinions at opposites of the apparatus, the parts being` proportionedsojthat the peripheral travel of the roller exactlyequals the lineartravel of the curtain, from which it is readilyseen that as the pulley47 advances forwardly on the ways 49, the upper run of ,the shuttercurtain 44 is vrolledacross the path of the The auxiliary support isthus formed by an anti-fraction devicey which does not imparthorizontalmovement to the sheetswhen said support is withdrawn to dropthe sheets onto `the platform or table 12.

As the roller 47 advances to extend the auxiliary support, the lower run4413 of the shutter curtain 44 unwinds from the drum 46 and passes overthe pulley 47 to provide the requisite length of curtain shutter for therun 44A, as heretofore set forth. But it is important to note that Whilethe lower run 44B of the curtain will have a longitudinal movementrelative tocthe Ways 49, the upper run 44A does not do so; any portionof the curtain, as soon as it becomes a part of the upper run, remainsstationary and fixed with respect to the surrounding parts, andparticularly with respect to any sheets that may be deposited thereon.lIn a similar manner, as the roller 47 is moved to its rearward position,so as to be'retracted from the path of the material discharged' from thecarrier A, the upper run of the shutter curtain 44 is rolled out fromunder any pile of sheets that may be superimposed thereon', thusventirely avoiding any sliding or frictional engagement with thelowermost sheet device, I provide an auxiliary support which may-bemoved into or out of the path ofthe sheets Withoutcausing a horizontaldisplace,- ment. of lthe pile of sheets.

.auxiliary support C, I provide a sprocket wheel 52 (Figs. 1 and 3)mounted on a shaft "52A journaled in a bearing on one of the posts 43,and a ratchet wheel 53 mounted on the shaft 52A with a pawl v54associated therewith for moving the roller 47 and shut,- ter, curtain44'to their extended positions. Asp'rocket chain 55 is operativelypassed over the wheel 52, iand then passes over pulleys 56 ig. 3)journaled suitably on the frame 17, so1D s to have one run 55A of thechain alined with and attached to one of the boxes 48, said run beingsubstantially coextensive with and parallel to the respective lways 49.The shaft 52A is provided with a detachable crank 64 (Fig. 2)'for manualoperation of the ,sprocket wheel 52, whereby the roller 47 and shuttercurtain 44 may be moved forwardly and into the path of the sheetsdischargedk from the carrier A, or rearwardly and out of the path f saidsheets.

Figures 1 and 3 show how the drum 46 is connected to an) operating shaft7y by meansA of sprocket Wheels 58 secured to said drum and shaft, and asprocket chain 59 lassing around said wheels 58. To rewind t- 1e curtainontosaid' drum, the shaft 57 has a square end (Figures 1 and 2) adaptedto receive the crank 64.

After the curtain 44 has been extended'it can be tightened, ortensiorfallyadjusted, by operating the shaft 57 to rewind a portion ofthe curtain onto the drum 46. To retain this adjustment, the shaft 57may be provided with a ratchet wheel cooperating with a pawl 65.

To limit the motionof the sheets delivered to the auxiliary support Cand platform 12, stops 61 (Figures 1 and 5j) are secured to a bar 62 atthe rear of the machine, and to .provide for' adjustment of said stops,the

bar 62f'is provided with extensions adjustable in-bearings '63. In theuse of the invention, it will be readily seen from the foregoingdescription that as the sheets are printed on the press .and transportedtothe platform, or table 12, by

ythe carrier A, theplatform will be lowered step by stepto'accommodatethe increasing depth of the pile of sheets thereon, and,at the roper`v time, .the roller 47 is moved forwardly 1nto the pathofthe sheets discharged from the carrier Athus rolling the shutter f'curtain 44 into sfaid path, andproviding an auxiliary support (Fig. 7 )1for the reception of the Msheets as 23A, whilelthe loaded platform isremoved and replaced/with an' empty one. The operator then elevates theempty platformv as high as the auxiliary support will permit, or as farasisdesirable, and

retracts the auxiliary support to the.posi, tion shown` in Fig. 6, thusthe sheets .23Av

are transferred Uby gravity to the platform. The platform may then, ifdesired be' further elevated, butl usually this is not necessary, as thesheets 23A temporarily supported on the auxiliary'support will sulice tobring the top of the pile to the proper distance below the discharge endof the carrier A.
